Abstract

This Standard was technically approved by the Gases Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on June 4, 2013. Available at www.semiviews.org and www.semi.org in July 2013; originally published November 2001; previously published November 2008.

 

The purpose of this Document is to define a test method to quantify impurity removal capacity of inert gas purifiers.

 

To determine the impurity capacity of a gas purifier at the point of breakthrough. Capacity tests are done by adding ppm levels of a given gaseous impurity to a pure zero gas and monitoring the effluent of the test purifier for active impurity species.

 

This Document is intended for point of use (POU) inert gas purifiers where inlet purity is 99.9995% or higher.
